Any Bosch sensor will work. I used an S4 sensor because the pigtail keeps the connection out of the muck. Because I have the auto retard circuit, I didn't need the EZ-F air temp sensor, so I reused it's wires to the EZ-F for the sensor.
I have since reduced the KnockLite sensitivity to 11 (1 is most sensitive). On the dyno, I unplug it.
The Vampire can retard individual cylinders, whereas my DIY circuit can only retard all the cylinders using the octane loop.
